A lightning arrester, also known as a lightning diverter or surge arrester, is a device designed to protect electrical and electronic systems from damage caused by lightning strikes or electrical surges. Its primary purpose is to divert the high-voltage lightning surge to the ground, preventing it from flowing through the protected system and causing potential damage.
Lightning arrester technology has evolved over time, and different types are available for various applications. The two most common types are:
Rod or Franklin-type arrester: This is the traditional design and consists of a tall, pointed metal rod placed at the highest point of a structure. When lightning approaches, the rod provides a preferred path for the lightning bolt to follow, directing it safely to the ground.
Metal oxide varistor (MOV) arrester: This is a more modern and commonly used type of arrester. It employs a series of metal oxide discs or blocks to divert the surge. The MOV arrester is connected in parallel to the equipment or electrical system it is intended to protect. Under normal operating conditions, the MOV arrester remains non-conductive. However, when a high-voltage surge, such as a lightning strike or power surge, exceeds a certain threshold, the varistor material becomes conductive and effectively shunts the excess energy to the ground.
Lightning arresters are commonly installed in various settings, including residential, commercial, and industrial buildings, as well as utility power systems, telecommunication networks, and other critical infrastructure. By providing a low-resistance path to ground for lightning surges, these devices help safeguard electrical equipment, appliances, and sensitive electronics from potentially catastrophic damage caused by lightning-induced voltage spikes.
